You have exquisite taste in names! I honestly couldn’t shorten down the lists as much as you wanted, but here are my favorite first names:

Imogen (prefer the way Imogene sounds because it’s spunkier)
Eliza
Maisie
Elodie
Emmeline
Beatrix
Louisa
Zara
Margot
Freya
Anneliese
Cecily
Florence
Delphine (absolutely adore this name, even for a middle name if not for the first name!)
Briony
